The Power System

After much research and budget consideration we decided on the power system.

Fan: Schubeler DS-75-DIA HDT 110mm Carbon Fiber 4 Bladed Fan
Motor: Neu 1527/2.5D 925kv
ESC: Castle Creations PH-110HV
Batteries: 12s1P 4900-6400mah 30C+

Thanks to some tests performed by Whistling Watts I determined that this combo would provide the desired thrust and speed that I need to reach my goals. At sea level, with an 85% exhaust pinch, the system should push with 14.5lbs of thrust and an eflux velocity of 240mph while drawing 112amps on 12s. Perfect! At our elevation we'll see about 12.3 lbs of thrust at 96amps, but the speed should still be there.

I know the Schubeler fan has a more offensive sound than other fans, but from what I've read, it's top of the line in efficiency and performance. Not to mention I don't have the $$ for a Stumax.
